Webauthority must be pointed to by several good hubs while a good hub must point to several good authorities. Further improvements and extensions of HITS were devel-oped in [16, 7, 11, 24, 8, 12, 26, 1, 4]. The goal of this paper is to give a detailed analysis of the HITS algorithm, focusing on the role of indegrees and outdegrees. i j j i Fig. 1.1.

Semantic Hubs and Authorities for Citation Analysis

Websimilar process and algorithm can be adapted when seeking “similar” webpages. A feature of Kleinberg’s algorithm that brought joy to fans of linear algebra is that the desired authority-weight and hub-weight vectors form, re-spectively, the principal eigenvectors of ATA and AAT, where A is the adjacency matrix of the WebHITS Algorithm. Similar to PageRank, HITS uses Link Analysis for analyzing the relevance of the pages but only works on small sets of subgraph (rather than entire web graph) and as well as being query dependent. The subgraphs are ranked according to weights in hubs and authorities where pages that rank highest are fetched and displayed.
